Hello, I am having the exact same problem with a 2018 G25E-7 and it would be great to hear more about how you were able to take care of it.

This machine will literally shut down 20-30 times in 24 hours, I blew all the dust out of the radiator and the coolant level is good but it makes no difference. We have two of the same machine operating in the same conditions and the other one works without any problems.

I didn't understand whether or not you needed software to see the error codes. As I type this out, I realized that when I performed the 'pedal maneuver' the check engine light flashed irregularly. Do I need to count the flashes? Unfortunately we don't have manuals for these forklifts, so I would really appreciate any info you can pass on. Thanks in advance,
